Show the internal dependencies in your OCaml/Reason/Dune project.
Input: the root folder of your project
Output: a graph in the dot format
Example:
$ dune-deps | tred > deps.dot
$ dot -Tpng deps.dot -o deps.png
Running dune-deps on itself gives us this dependency graph:
This is the graph we obtain for the source code of opam, an elaborate project of over 50K lines of code:
From opam:
$ opam update
$ opam install dune-deps
From the git repo:
$ make
$ make test
$ make install
For producing a 2D image of the graph, we rely on the dot command
from Graphviz.
Additionally, it is often desirable to remove excessive edges to make
the graph more readable. We consider "excessive" an edge that can be
removed without changing the reachability from a node to another. This
transformation is called
transitive reduction
and is performed by tred, normally installed as part of the Graphviz
suite.
